/** <p>
 * This class demonstrates some aspects of the OWL API. It expects three
 * arguments:
 * </p>
 * <ol>
 * <li>The URI of an ontology</li>
 * <p/>
 * <li>The URI of destination</li>
 * <p/>
 * <li>The URI of a class</li>
 * </ol>
 * <p>
 * When executed, the class will find all subclass axioms that form part of the
 * definition of the given class. For each of these, if the superclass is a
 * conjunction of existential restrictions, then an additional subclass axiom
 * will be added to the ontology, "closing" the restrictions.
